The Shadowless Edge is one of the best dual-wielded weapons in Phantom Blade Zero.
It's a great weapon that features high combat mobility, exceptional guard break capabilities, and massive damage buffs. Thanks to its Dual-Blade Flurry skill, Sha-Chi Essence is able to dissolve into a black crow and sweep forward to deal an unblockable attack.

How to Get the Shadowless Edge in Phantom Blade Zero
To get the Shadowless Blade, you need to soul-temper the Sanguine Twin weapon using the Chaos Fragment I.
You get the Sanguine Twin in the Weeping Creek Valley region. Advance through the main story until you meet Yu'Er in the forest area, where she gives you the Flesh Lily quest. After your conversation with her, continue along the path. However, instead of going up the main trail, look to the right, and you'll find a massive wooden water wheel.
At the back of the cliff, head down into the alcove. You'll spot a small waterfall and a wooden ladder next to it that leads to a Rift Bell. The Sanguine Twin can be found sitting on a wooden weapon rack at the foot of the waterfall.

To get the Chaos Fragment I, you'll need to head to Meigu Leak and enter the Discordance Realm. Once there, navigate the base of the cliffs until you stumble across an iron gate. With your Dread Axe, destroy the gate to claim the Chaos Fragment I.
Once done, go to Myst in Pangzhen. Speak with them to Soul Temper your Sanguine Twin to Shadowless Edge. You'll need to use the Chaos Fragment I and some Remnant Dust to switch the weapons.
